Re: Motherboard recommendations?

I am about to buy a new motherboard (preferably Intel) for a desktop
computer and would like to check NetBSD compatibility before buying.
I am about to ask the same question. I think the best bet is to see
reports from others who are happy.
1) Since spring/summer/fall 2010, I have had a whole lab full (growing to
20) of:
cpu0 at mainbus0 apid 0: Intel(R) Core(TM)2 Quad CPU Q9650 @ 3.00GHz, id
0x1067a
cpu1 at mainbus0 apid 1: Intel(R) Core(TM)2 Quad CPU Q9650 @ 3.00GHz, id
0x1067a
cpu2 at mainbus0 apid 2: Intel(R) Core(TM)2 Quad CPU Q9650 @ 3.00GHz, id
0x1067a
cpu3 at mainbus0 apid 3: Intel(R) Core(TM)2 Quad CPU Q9650 @ 3.00GHz, id
0x1067a
acpi0 at mainbus0: Intel ACPICA 20110623
acpi0: X/RSDT: OemId <INTEL ,DQ45CB ,00000077>, AslId <MSFT,00010013>
running netbsd-5 and now netbsd-6, amd64, which have been pesky wtih X
and have radeon cards because of it. There have been occasional
hardware issues. But generally they have been fine.
2) For about a year and a bit (I think) I have a DH67CL with a quad-core
i5:
mainbus0 (root)
cpu0 at mainbus0 apid 0: Intel(R) Core(TM) i5-2310 CPU @ 2.90GHz, id 0x206a7
cpu1 at mainbus0 apid 2: Intel(R) Core(TM) i5-2310 CPU @ 2.90GHz, id 0x206a7
cpu2 at mainbus0 apid 4: Intel(R) Core(TM) i5-2310 CPU @ 2.90GHz, id 0x206a7
cpu3 at mainbus0 apid 6: Intel(R) Core(TM) i5-2310 CPU @ 2.90GHz, id 0x206a7
ioapic0 at mainbus0 apid 0: pa 0xfec00000, version 20, 24 pins
acpi0 at mainbus0: Intel ACPICA 20110623
acpi0: X/RSDT: OemId <INTEL ,DH67CL ,01072009>, AslId <AMI ,00010013>
with 16G RAM (memconf):
Intel Corporation DH67CL (Quad-Core Intel Corporation Intel(R) Core(TM)
i5-2310 @ 2.90GHz)

on which I am running netbsd-6/i386 (because I upgraded hardware with
dump/restore and haven't gotten around to switching to amd64).
I have run X, but it's a little funny. I've had enough trouble with X
on various systems lately that I don't remember exacctly; it might be
that after the X server exits I can't restart it. But I have radeon
card plugged in, probably because I had trouble with the built-in
graphics earlier.
Things are mostly ok, and worked with netbsd-5. I am having some
stability problems, but I don't think it's the mobo design. I was
having lockups under heavy load, with some apparently misaddressed
writes after rebooting. I replaced a disk which helped a lot - zeo
crashes since. It has since failed memtestplus when run with all 4
cores, and I'm going to swap out the memory, and if that doesn't work
just get an entirely new system (this is at work) and diagnose the old
one in the background.
I use the included wm0:
wm0 at pci0 dev 25 function 0: PCH2 LAN (82579V) Controller (rev. 0x05)
wm0: interrupting at ioapic0 pin 20
wm0: PCI-Express bus
wm0: FLASH
ihphy0 at wm0 phy 2: i82579 10/100/1000 media interface, rev. 3
and it works fine. I also send 8-bit mulaw audio via /dev/audio to
speakers and that works fine.
I am looking forward to DRM/KMS. Perhaps Taylor could explain what
chipsets are likely to be ok, but I have the impression that "modern
Intel" is the first target.
I would be interested in a motherboard with at least 4, maybe 8 cores
and 32G of RAM, that works with the brave new world of DRM/KMS.
And I'd like a few PCI (really PCI) slots still, although I realize
that's getting somewhat rarer.
3) The D915GEV is rock solid. I have two of them, and one has been up
for over a year. But it's from 2006, too slow/etc., and surely you
can't buy one.
